From a simple pilot's perspective - I have flown Robin, DA40, DA42 (classic stick), Columbia 400 (sidestick) and SR22 (Side-Yoke).
I never found the transition hard, in fact the Columbia sidestick was a delight - but if I remember correctly, the Columbia side stick forward/aft direction is slightly angled to align with your arm movement, not the aircraft axis. I might be mistaken, though - Genghis, do you know?
The Cirrus thingy is not angled, and it needs a slight breakout force to initiate a roll which I personally found awkward - now that I read your experience that might be to prevent inadvertent roll inputs when pulling/pushing.
